1 Claim.

(Granted under the act ofMarch amended April 30, 1928; 3'70 0.

looped band of steel or a half loop.

This application is made under the act approved March 3, 1883, as amended by the act of April 30, 1928, and the invention herein described may be manufactured and used by or for the Government for governmental purposes without the payment to me of any royalty thereon.

I hereby dedicate the invention herein described to the free use of the Public, to take effect upon the granting of a patent to me.

My invention relates to that class of instrument used in marking or scribing the trunks of trees that are to be worked for their resin. It was devised for designating the side of the tree upon which the first installation of cup and gutters are to be made and to properly mark the bounds of the face of the tree for several seasons work.

I have found that by pulling the tool, hereinafter more fully described, down the trunk of the tree, a mark or groove is made in the bark. This mark or groove delimits the size of the face which is to be cut on the tree by the woods worker, known as a chipper.

The value of my device is that it provides a definite outline of the proper size of the face, which size is determined mainly by the diameter of the tree.

My invention is so devised that it will take care of the size of the tree, the ratchet, hereinafter more fully described, permitting the scribing of faces of any width desired.

My invention in addition to being a practicable tool is one that requires in its use little experience and a man can work off several hundred faces a day.

By referring to the drawings: Fig. l is a plan view; Fig. 2 is a front elevation; Fig. 3 is a side view; Fig. 4 is a plan view of the ratchet assembly; Fig. 5 is a side elevation of the ratchet assembly; Fig. 6 is a perspective view of my invention, showing the manner in which it is used.

Figs. 4 and 5 show a modification of my device set forth by Figs. 1 to 3.

Similar letters refer to similar parts throughout the several views.

Two arms (Wood or steel) B, hinged at one end by means of a joint A, which is made of brass or other metal capable of making a smooth, durable and easily operated joint; having cutting blades G, made of a looped band of steel with lower edge sharpened and forming a V or U shape at end of each arm and attached thereto by means of metal shank J fitted into metal frictionless collar E, which fits into brass bushing F. Cutting blades G may be a full Metal shanks J extend through collars E and form the cores of handles H, which may be made of wood or of other composition so shaped to fit the grip.

rods C, which are attached at the joint of the arm, so that the left rod is attached to right arm of tool, and ri arm of tool by means of hinge ght rod is attached to left collar E, in order that cutting blades G are automatically kept perpendicular to the center of the tree, regardless of the spread of cutting blades G. Turn knuckle K is located midway of each rod for adjusting the length of guide rods C.

guide rods C.

In this event, cutting blades G are held in place a set screw of ratchet assembly M (Fig. 4).

Metal shield I is attached to handles H by conventional means to protect the operators knuckles.

Graduated scale D attached to arm B by means of bolts L is of brass of other thin metal and is graduated into inches or other convenient units of measurement to indicate the distance apart of cutting blades G.

In operation the operator grasps the tool with his hands at points H with the blades G pointing away from him.

The adjustment of the tool is accomplished by exerting an outward pull on the handles H when a wide face is to be scribed, or

an inward pressure when a narrow face is scribed, dependent on the diameter of the tree, approximately 4 feet above the ground.

After the tool is adjusted to the desired width,

the operator raises proximately 5 fe places the two cutt (Fig. 6). The tool against the tree t the tool to a height of apet above the ground and ing blades against the tree is then forced downward and within substantially ten A turpentine-face scribed, comprising scribe, of the character dea plurality of arms pivoted together at one end; handles mounted at the opposite end of sai d arms; shields carried by said handles; cutting blades pivotally mounted on said arms and near said handles, said blades having their cutting edges extended toward a common point, and

means adapted to maintain said relative position of the blades as said arms are adjusted.
